Centrifugal fixture



June 24, 1930. c. cs. HAWLEY CENTRIFUGAL FYIXTURE Filed May 4. 1925 Patented June 24, 1930 UNITED STATES PATENT OFFICE CHARLES GILBERT HAWLEY, OI GHICAGO, ILLINOIS, ASSIGNOR '1'0 GEN'IRIFIX COR- PORATION, OF CLEVELAND, OHIO, A CORPORATION OF OHIO CENTRIFUGAL FIXTURE Application filed May .4,

My invention relates to separators for use in extracting or separating moisture and solids from steam,.air and gas lines and the object of the invention is to provide a combined centrifugal separator and drip pocket for use in horizontal lines or pipes; and which shall be of a simple and convenient construction of relatively small size and little weight and highly efiicient.

The structure embodying the invention and the manner in which the aforegoing objects are attained will be clearly understood on reference to the drawing which forms part of this specification; and in which, Fig. 1 is a vertical section of a centrifugal fixture or separator embodyin my invention. Fig. 2 is an enlarged longitudinal section of the tuyere plug which comprises one of the two parts of the separator;

- Fig. 3 is a vertical section on the line 3-3 of Fig. 2; Fig. 4 illustrates a slightly modified construction intended to suppress or lessen the evaporation of the m oisture'collected in the drip pocket during periods of idleness; and Fig. 5 is a vertical section on the line .55 of Fig. 4.

The pocket ortlon of the separator comprises the poo et proper 2 and the substantially cylindrical head 3 which is integral therewith. The axis of the head is horizontal.. The axis of the pocket is vertical. The cavity 3 within the head obviously forms the top of the drip pocket 2. One end of the head contains a large threaded hole 3 which receives the tuyre plug 4 about to be described. The other end'of the head 3 contains the small central outlet 3" and is threaded to receive the outlet pipe 5. Prefend of the outlet 3 is distinguished by the circumferential lip 3 The surface surrounding the lip 3 is flat and transverse to the axis of the head. pocket is threaded to receive a plug or valve 6 through which the pocket is drained.

The inlet or supply pipe 7 is threaded into theend of the plug ,4 so that the pipe communicates with the internal cavity 4 of the .plug. The plug itself has a stop shoulder 4 and a threaded portion 4 which fits the erably, though not necessarily, the inner The lower end of the 1925. Serial No. 27,864.

thread 3*. The plug is of such length that the'inner end 4 thereof reaches almost to the surface 3 leaving only the circumferential gap or race 4 bet-ween them. Initially the end 4 of the plug is machined to a thin edge 4 and provided with a shoulder 4". Afterward, the disk or ring 4 is placed on the seat or shoulder 4" and the thin edge 4 is peened or spun down to hold the ring as shown at point 8 in Fig. 2, and also in Fig. 1. At the same time that the shoulder 4 is formed the integral disk 4 within the plug is machined. That disk is connected with the body of the plug by two or more arms leaving the clear openings 4* at the periphery of the disk 4 The ring 4 contains a central hole 4" slightly larger than the disk portion 4 When the disk4 is fastened in place it serves to secure the tangential tuyere ring 4, the inner end of the ring being seated against the shoulder of the part 4 and the outer endagainst the disk 4, as well shown 7 in Fig. 2. The ring 4. is made from a strip of metal which is cut and pressed to form the many tangential tuyere blades 4" between which are the many tangential tuyeres 4' It is of much convenience that the tuyere plu .may so easily be removed from the drip poc et at times when it should be inspected or cleaned. I

Pressure fluid that is admittedto the interior of the plug enters the ring 4* through the many tangential tuyeres 4 and is thereby set into rapid rotation. The effect is to centrifugal'ly separate the heavier substances carried by the fluid and to throw them out into the race 4?, thence to fall into the pocket 2 while the purified fluid ,departs through the outlet 3". These small separators find use in many places and are particularly desirable when used in advance of pneumatic hammers and like tools, the same serving to extract the moisture and solids from the compressed air before it is allowed to enter the tool.

' Having thus described my invention I claim as new and desire to secure by Letters Patent 1. A generally cylindical member open at both ends and containing an integral transverse disk, in combination with a ring sealed in the end of said member and having a central opening coaxial with said disk and a multiple tangential tuyere held between said disk and said ring.

2. A combined centrifugal se arator and drip pocket, comprising a mem er containing a drip pocket'and having a transverse head portion, the latter having a large opening'in one side and a smaller outlet in its opposed side, in combination with a fluid g whirling member positioned between said openings, a hollow plug held in the larger side opening, containing at its outer end an inlet opening and itself forming an enclosure for said fluid whirling member, and said member being spaced from but opposite to said outlet, whereby the fluid entering the plug is caused to flow first inwardly through the fluid whirling member and thence to said outlet across the space between said member and outlet to centrifugally eject the separated substances into said pocket.

3. A horizontal line separator comprising a vertically extended pocket having a drain hole at the bottom and at the top provided with a transverse head portion the lower side of which opens into the upper part of said pocket, said transverse portion having a large opening in one end to receive a tuyere enclosing plug and coaxially a smaller opening in its other end, in combination with a fixed fluid entrance tuyere mounted in said plug which is coaxial with said large opening and which presents an open end toward but in longitudinally spaced relation to said smaller opening, said tuyere including a circumferential series of inclined blades between which the fluid flows inwardly and, taking on a whirling motion within the tuyere and in the space between the same and the smaller opening. results in centrifugally separating the heavier substances carried by the fluid and their discharge into said pocket.

In testimony whereof I have hereunto set my hand this 30th day of April, A. D. 1925.
